I want to get pregnant..

We've been married a year and a half.. We both really want kids, husband wants to wait at least a year and a half more to start trying. Ive just scored a good job so I feel more ready now than ever..

Really, I just dont know how to bring it up to him. We've talked about it before, and my husband has said 'i cant wait'... but hes not ready yet. He wants to start a business and buy our first home together first.

P.s. - awhile ago, we were doing the pullout method but stopped... He even came in me once. We were doing it for about 2 months... I have had a pregnancy 'scare' and thats when we stopped... but nothing has ever happened.... does this mean I have fertility problems??
